Ok so a few weeks ago I got up to 370x5 reps, pretty happy with that, next week I got 4 reps...week after 2, so I decided to take a break after 5 months of lifting. I took 2 week off before I did deadlifts again. Today I did them, I usually do 135,225,315,350(in todays case) for 6 reps, i got to my third set(315) and it was hard to get 6!?!?! I didn't even end up doing the fourth set, can someone PLEASE HELP!
